I have a question - sometimes when I've been to websites that don't look so safe (for example, downloading mods for Skyrim from Russian or Chinese sites), I'll click on something on the webpage, and a new tab will open and close immediately in Chrome. Is this a security concern, or is my Chrome pop-up blocker just shutting down a pop-up ad for another site, or what? I have Avast and also have used Malwarebytes safe browsing add-on in the past, and neither have responded, and no virus or malware scans ever show anything...in addition, I'm using a VPN. .. but it still makes me nervous...so does anyone know what this might be? Thanks!
